relationship with each other.

Still more particularly, the invention deals with a box member havingmeans for angularly supporting the slider when brought into abuttingengagement therewith to provide proper alinement of the pin part withthe box part of the separator to facilitate freeand easy coupling anduncoupling of the pin and box parts.

The novel features of the invention will be best understood from thefollowing description, when taken together with the accompanyingdrawing, in which certain embodiments of the invention are disclosedand, in which, the separate parts are designated by suitable referencecharacters in each of the views and, in which:

FIG. 1 is a diagrammatic plan and sectional View of the box and pinstructure of a pair of stringers illustrating initial engagement of thepin part with the box part in coupling the stringers.

FIG. 2 is a view, similar to FIG. 1, showing the pin part in a furtheradvanced position in the box part.

FIG. 3 is a view, similar to FIGS. 1 and 2, showing the box and pinparts in elevation and illustrating a still further advanced position ofthe pin in the box part.

FIG. 4 is a View, similar to FIG. 3, showing the pin and box parts fullycoupled and indicating, in part, the slider partially withdrawn from thepin and box parts.

FIG. 5 is a section substantially on the line 5-5 of FIG. 3 on anenlarged scale; and

FIG. 6 is a section substantially on the line 6-6 of FIG. 4 on anenlarged scale.

In the accompanying drawings, I have illustrated, in part, at 10, 10'part of a pair of stringer tapes, to one surface of which are securedcoil fastener elements 11, 11 by stitching, as diagrammatically seen at12, 12'. Looped ends of the coils project beyond the adjacent abuttingedges of the tapes 10, 10', as clearly indicated by the abutting tapesat 13, projecting portions of the coils having offset interlockingelements 14, 14', as clearly illustrated in FIGS. 1 to 4, inclusive, noattempt being made to show these portions in the diagrammaticillustration of FIG. 6.

At 15 is shown the slider for coupling and uncoupling the stringers. Theslider comprises two walls 16 and 17, note FIGS. 5 and 6, having'sideflanges 18 and 19 respectively, forming the contour of the channel ofthe slider body which diverges at the wide end 20 of the slider body,which end has, centrally thereof, the connecting web 21 separating thetwo channels, as with other structures of this type and kind.

The cross-sectional contour of the slider body. is such as to bring thetapes into a position substantially centrally of the sides of the sliderbody, Where the tapes pass through the side openings 22. It will also beapparent, from a consideration of FIG. 6, that the inner surface of thewall 16 of the slider is recessed, as seen at 23, to

3,170,207 Patented Feb. 23, 1965 clear the stitchings 12, 12', therebypreventing wear on the stitches in the operation of the slider along'the stringers.

At the separator end of the fastener, the stringer tapes 10, 10' havetheir ends .folded, as illustrated at 24, 24

g in FIG. 5, and thetapes are reinforced by additional tapes 25, 25',which are stitched to the tapes 10, 10' including the folds 24, 24'therein. This construction 10- cates the tapes 10, 10' in substantiallythe same relationship as the tapes as they appear in FIG. 6 of thedrawing. Cast or otherwise secured on the end portions of the tapes 1t),141', including the reinforcements 25, 25', are box and pin parts 26, 27of the separator.

The side portion of the stop or box part 26 secured to 10-25 includes aninwardly projecting reduced portion 28, having an integrally projectinghook 29, the hook forming a recess 30 on the inner surface thereof. Thehook 29 projects from the surface 31 of the pin engaging socket orchannel 32 of the box part 26, the channel being partially defined byside flanges of the box part, one of which is seen at 33.

The pin part 27 has a rounded exposed surface 34 terminating at arecessed portion 35 in a rounded corner 36. The pin part 27 extendsbeyond the edge of the reinforcement 25' and has a projectinginterlocking finger or lug 37, which partially forms the recess 35. Thelug 37 has a rounded projection on one side surface thereof, as seen at38, and a recess 39 on the opposed side surface thereof, 38 operating inconjunction with the recess 30 and an end loop on the coil 11, or theelement 14 thereof engagesthe recess 39, as seen at 14" in FIG. 4 of thedrawing, when the pin and box parts and the stringers are coupledrelationship to each other, this figure also clearly illustrating theengagements between 38 and 30 and the arrangement of the hook 29 withinthe recess 35. The box part 26, at its outer end, is generally of thecontour clearly shown in FIGS. 3 and 4 of the drawing and is of greaterthickness than the extension 28 thereon. This greater thickened portionhas, on its inner surface, angularly disposed walls 40, against whichthe contracted single channel end of the slider operates, as will belater described.

Considering'FIGS. 1 to 4, inclusive, it will be apparent that, in theoperation of coupling the pin part with the box part, preparatory toengaging the stringers, the slider 15 is brought into engagement withone of the angular surfaces 44}, as illustrated in FIG. 1 of' thedrawing, at which time the pin part is moved into the position,substantially as seen in said figure and, in continuing this inwardmovement of the pin part, the slider is swung from the position shown inFIG. 1 to a'position substantially as seen in FIG. 2 and this movementis further continued until the lug 37 or the projection 38 thereonstrikes the hook 29, as seen in FIG. 3 of the drawing. This checkscoupling engagement of the pin part with the box part, after which theuser operates the slider, moving the same from left to right or, inother words, from the position of FIG. 3 to the position of FIG. 4, inwhich last operation the slider moves the pin part 27 into coupledengagement with the box part or, in other words, with projection 38 onthe lug 39 in engagement with the recess 3% on the hook 29 and with theelement of the end loop of the coil 11 engaging the recess 30, asillustrated at 14". With the parts in this position, it will be apparentthat the stringers are securely coupled against separation adjacent thepin and box parts.

In uncoupling the pin and box parts, it will be apparent that the slideris moved from the position of FIG. 4 into the position shown in FIG. 3,in which position the coils 11, 11 of the stringers are separated by theslider, after which the pin part 27 is withdrawn from the box part or,in other words, moved from the position of FIG. 3 to the position ofFIG. 2 and, then, finally out through the slider when the slider is inthe position shown in FIG. 1. The above description describes the stepfashion of continued operation between FIG. 1 and FIG. 3 and from FIG. 3back to FIG. 1, it being understood that an independent operation isrequired to control movement of the slider from FIG. 3 to FIG. 4 andvice versa.

From the foregoing, it will be apparent that the wall 17 of the slider,including its flanges 19, operates on the stringer tapes; whereas, thewall 16 and its flanges 18 operate upon the coils 11, 11'. By minimizingthe space between adjacent surfaces of the flanges 18 and 19, not onlyis the tape centrally located, but substantial thicknesses of the boxand pin parts are made possible for engagement with the tapes, includingthe reinforcements 25, 25', as will be clearly apparent from aconsideration of FIG. 5, the thicknesses illustrated being those of thepin part and the reduced extension 28 of the box part, upon which thecontracted end of the slider operates. It will be understood that thereinforcing tapes 25, 25' are stitched or otherwise secured to the tapes10, 10, including the folded-over portions 24, 24' and the stitchingsare diagrammatically illustrated at 41, 41 in FIG. of the drawing.

Considering FIG. 5 of the drawing, it will be apparent that the roundedcorners of the pin part and the reduced extension 28 of the box partoperating in conjunction with the rounded surfaces of the flanges 18 and19 will provide for free movement of the pin part inwardly and outwardlythrough the box part and, in FIGS. 1, 2 and 3 of the drawing, clearancesbetween 27 and 28 and the flanges 19 are illustrated by the dotted lineshowing of the flanges 19 in said figures, it being understood that theillustrations are diagrammatic.

For the purpose of this document, the right end of the pin and box, asseen in FIGS. 1-4, shall be considered the inner or inward end of theseelements and the opposite or left end, as viewed in these figures, shallbe considered the outer or outward end of these elements.
